L4 Flashcards
Bubble around assessment
exam, problems, diagnosis, risk– prognosis – solutions based on those
what makes up stabalization therapy
- core build ups/ post and cores
- crown lenghtening
- perio or prosth reasons - special preps and perio treatemnts
- grafts
- osseous surgeries
- root amputations / hemi sections - endo
- implants
- interim restoratinos
re-evaluation
3 situations where could be considered definitive / stand alone and what makes it that way?
- oral surgery
- ortho
- perio therapy - like soft tissue graft
BUT NOT FOR THE PURPOSE OF SUPPROTING RESTORATIONS or achieving / restoring health
core build up rationale
- replace missing tooth structure
- post retains the core
- core adds resistance form to the prepared tooth
- composite depends on bonding to ?? (enamel)
amalgam depends on RETENTION so there has to be some after the tooth is prepared
when using composite or amalgam for core build ups – they depend on?
composite depends on bonding to ?? (enamel)
amalgam depends on RETENTION so there has to be some after the tooth is prepared
make or break of endo treated teeth
Ferrule
two main reasons for crown lengthening
- prosthetic reasons
- do not have enough tooth structure - periodontal
- biologic width reasons
prosthetic reaons for crown lengthen
short clinical crowns
compromised retention
prognosis improved
affects retention
ease of maintenance
impression ease
waht comes first the crown prep or the CLP?
Crown prep has to preced the clp so that adequate bone can be removed to re-establish biologic width and ferrule
gingival recession
exposure of the tooth root due to loss of keratinized tissue around the neck of a tooth
free gingival graft
taking small layer of tissue from the PALATE and suturing it over to the site of gum recession
INCREASE KERATINIZED TISSUE
better than a free gingival graft?
subepithelial connective tissue graft – more predictable coverage for root coverage and more esthetic outcome — tkae tissue from under healthy gum rissue in the palate
what stage in millers gingival recession classification do you lose the papilla?
past stage II (so not stage II but stage III)
miller classification of recession
i – recession that has NOT extended to the MGJ – no bone loss
ii– recession to or beyond MGJ – NO bone loss
iii — recession to or beyond MGJ BONE LOSS AND PAPILLA RECESSION
iv — recession beyond the MGJ and bone los to the base of recession defect
describe root amputation
can preserve periodontally failing
allows the motivated patient to clean and area that otherwise would be maintainable
non-odontgenic pain
rule out TMJ, occluion, oral sores, perio causes
reversible pulpitits symptoms
sensitivity to hot, cold and sweets
does NOT linger
localized to a tooth
irreversible pulpitis symptoms
sensitive to thermal stimuli
lasts after stimuli is removed
can be spontaneous and difficult to localize
necrotic / non-vital symptoms
thermal, electrical pulp tes and finally cavity
occurs corono-apically – may be vital tissue in parts of the root system
abscessed symptoms
swollen periapical tissue – yields a tooth that is high and sensitivity to percussion
what encompasses oral surgery procedures in tx plans usually
- removal of hopeless teeth
- promote heling to allow for definitive care
- correction of intra oral anomolies - tuberositites, flabby ridges
- augmentation of the jaw to support restorations
stabalization ortho procedures?
for implants
interim restorations
to correct tooth position and regain guidance
stabalization / support therapy for interum restorations?
- transitional dentures
- transitional partial dentures
- restorations
transitional dentures = immediate?
NO –
when are composites or amalgams not definitive
when used as interim restortions and a crown is the better long term – definitive tx plan
definition of caries control
removal of decay in the teeth for the purpose of stopping the progression of a contagious event
allow treatment to proceed in other area until such a time has passed to allow defintiive therapy to be performed in a predictable fashion to the affected teeth
IRM =
intermediate restorative material
ZOE -IRM?
zinc oxide eugonal - IRM
contraindications for ZOE-IRM?
demonstrates high interfacial LEAKAGE so contraindicated in direct pulp cap / use with resin components
glass ionomer description
provides an excellent bacterial seal and shown good bio-compatibility when used in close approximation BUT NOT IN DIRECT CONTACT WITH THE PULP
KEY TO PULP SURVIVIAL AFTER CAPPING?
well sealed restoration
